Masjid al-Ḥarām · 24/7 from the Sacred Mosque
Broadcast by the Saudi General Presidency for the Affairs of the Two Holy Mosques. Continuous, official, and free. The feed is live almost all the time, during the rare moments when the live stream is offline (typically only during major maintenance), YouTube auto-falls-back to the channel's most recent recording, which is also from the Ḥaram.
Watching the live broadcast is not a substitute for prayer or remembrance. Treat the stream the way you would the ḥaram itself, with adab, lowered gaze, and presence. The audio plays in the background, keep it running while you read Quran or do dhikr.
